Mayor of Boston Coun Alison Austin reopened the school’s ‘traditional heart’, one of many victims of the December 5 tidal surge that hit the town.

Headteacher John McHenry said: “The school is very grateful to all those who have supported us throughout this time. It is reassuring to be reminded of the school’s character and resilience.”

The December floods caused ‘significant’ damage to the school including the 450 year old library which dates back to 1567.

The library’s flooring needed careful restoration by a specialist company, and it took several months to ‘dry’ the building as usual techniques couldn’t be used due to the age of the beams.

Most of the artefacts in the school’s museum were moved as a precaution, though some were damaged.

Mr McHenry said: “Thankfully nothing was lost completely. Many of the artefacts are irreplaceable, including early school reports and photographs.”

The mayor was joined by chair of governors Phillip Bosworth, chair of foundation governors Brian Pycock, ex-chairman of governors Jim Howes, governorMick Todd, Old Bostonian Association member Peter Sharman, pupils and members of staff.

The school has received help, work and support from organisations such as Old Bostonians, Bakkavor, Cucina Sano and Graham Gill Carpets.
